Native external references
The Native external references feature enables seamless integration of content from external sources directly into your content model, utilizing Contentful’s Graph API for data resolution. By leveraging existing reference fields in the content model and the App Framework, you can connect to third-party systems and import content directly into Contentful. Native external references use the standardized ResourceLink object entity to store references in a standard format which is native to the Contentful platform.
Note: Native external references and Apollo Federation are not compatible, and there are no plans to support them together.
You can create your own app to support Native external references using Functions. For more information on how you can build an app, see the example tutorial.
